Iris pallida 'Aurea Variegata', aka "Zebra"
'Spring Bliss'.. I have pictures of it in bloom last year from March, June, July, September, October & November... and it had buds in January that got wet and rotted and foiled it's winter bloom.
'Dynamite'- picture says it all.. Abundant, large flowers.. long bloom.
'Splashacta'- early, prolific, and long bloom.
It's a tie between 'That's All Folks' and 'Smart Money'.. This color makes me happy.
...and of course my beloved purple plicata NOID that I've had forever. I've got several clumps and it looks good with everything. Outperforms most other Iris in the garden, and has a stately presence.
I'm also fond of: 'Indian Chief', 'Quaker Lady', several blue NOIDS, Pledge Allegiance, a large yellow historic NOID... Oh gosh.. it's endless... There were many that I got last year that I just swooned when I saw them bloom.. Ask this again in a year, and I'm sure I'll have more additions.
